A nurse in a provider's office is talking with a client who takes oxybutynin. The client asks why he does not urinate as often. Which of the following information should the nurse include about the action of oxybutynin?
The medication reduces the rate at which the kidneys filter waste.
The medication decreases the sensitivity of the urethral sphincter.
The medication prevents the bladder muscles from involuntarily contracting.
The medication blocks the nervous system impulse to produce urine.
The Correct Answer is C
A. The medication reduces the rate at which the kidneys filter waste: This is incorrect as oxybutynin does not affect kidney function or the rate at which kidneys filter waste.
B. The medication decreases the sensitivity of the urethral sphincter: This is incorrect because oxybutynin primarily affects bladder muscle contraction, not the sensitivity of the urethral sphincter.
C. The medication prevents the bladder muscles from involuntarily contracting: This is correct as oxybutynin is an anticholinergic medication that reduces involuntary bladder contractions, leading to less frequent urination.
D. The medication blocks the nervous system impulse to produce urine: This is incorrect because oxybutynin works by blocking the action of acetylcholine in the bladder, not by blocking impulses to produce urine.

Correct Answer is C
Explanation
A. "I will have hot, dry, and flushed skin if I am having a heart attack": This statement is incorrect as it does not accurately reflect typical symptoms of a heart attack. Common symptoms include chest pain, shortness of breath, and possibly cold sweat, not hot, dry, and flushed skin.
B. "I will wait 30 minutes before taking action if I have heartburn": Waiting 30 minutes before taking action is incorrect for angina or heartburn. Immediate action is required for angina symptoms, and heartburn should be differentiated from angina by a healthcare provider.
C. "I will notify emergency response if I have sudden jaw pain": This statement is correct because sudden jaw pain can be a symptom of angina or a heart attack, indicating that immediate medical attention is needed.
D. "I will take four nitroglycerin sublingual tablets if I have chest pain": This statement is incorrect as taking four nitroglycerin tablets is excessive and could be harmful. The standard recommendation is to take one tablet every 5 minutes for up to three doses if chest pain persists, and then seek medical attention.
